Abstract: A mobile communication apparatus having a recording/reproducing function. The object is to record a greater amount of speech by recording a voice with a reduced amount of memory and to reproduce the recorded signals into original voices, when loading a recording/reproducing function into the mobile communication apparatus. There is provided a recording/reproducing section capable of recording either digital speech signals compressed in a digital speech signal processing section provided in the mobile communication apparatus which digitally performs a communication or compressed digital speech data transmitted from the other party in communication by way of a base station. The thus recorded compressed digital speech data may be supplied into the digital speech signal processing section for the reproduction on the side of the local central office or may be transmitted to the base station for the reproduction on the side of the other party in communication.
